Pharmacokinetic studies of amino acid analogues of 2-nitroimidazole, new hypoxic cell radiosensitizers.


A series of new analogues of 2-nitroimidazole has been synthesized by inserting various amino acids at 1-position through an amide bond. The ethyl esters of N-alpha-[(2-nitro-1-imidazolyl)acetyl]-L-phenylalanine and N-alpha-[2-nitro-1-imidazolyl)acetyl]-L-tyrosine were found to be the most effective radiosensitizers in vitro against hypoxic Chinese hamster… (More)
